2026 Tesla Model S Plaid: home charging cost in Iowa

A 2026 Tesla Model S Plaid draws 30.6 kWh per 100 miles per the EPA; at Iowa's 13.77¢/kWh residential rate that's $4.21 per 100 miles charged at home, versus $16.02 for a 25.5-mpg gas car covering the same distance. Charging at home costs a fraction of what gas would here: 73.7% less than gas per mile, here specifically.

Annual cost, at 15 thousands miles a year

Next step: home charger installation

The numbers above assume Level 2 home charging is already in place — the electrical work behind that is a real, separate cost that varies by panel, wiring, and local labor rates, not something this page's per-mile math includes.

Ask a licensed Iowa electrician to quote the install before this math becomes a real decision.
